UNITED STATES JACOB J'. TRANCHELL, OF PORTLAND, OREGON AUTOMOBILE HEATER Application filed August 25, 1927. Serial No. 215,458.

My invention relates to automobile heaters and it is an object 'of the invention to utilize the heat of the exhaust gases discharged into the muliier for heating the air Within the automobile as such air is circulated around said muffler all as will be hereinafter more fully described and claimed.

Referring to the accompanying drawings which are made a part hereof and on which 10 similar reference characters indicate similar parts,

Figure 1 is a side elevation illustrating one application of my invention,

Figure 2, a perspective of a register con- 15 structed in accordance with my invention,

Figure 3, a longitudinal view partly in section illustrating the application of my casing over the mufiier, and,

Figure 4, a transverse section on the line 30. 4-4 of Fig. 3. 'i

In the drawings reference character 10 indicates an internal combustion engine having an exhaust pipe 11 terminating in a muiller 12 beneath the body 13 of a sedan or 25, closed type automobile having front and rear seats 14 and 15 respectively. About the muffler 12 is secured a hollow casing comprising an inner sleeve 16 provided with overlapping edges to render the same variable 3Q in size and having its front end crimped over the front end of the mufiler as shown in Fig. 3. The rear end of this innei` sleeve is preferably left open or uncrimped so that any fumes escaping' from the mufiler may f3? pass out between the external surface of the muiiier and the interior of the inner portion of the inner sleeve 'into the atmosphere. Around this inner sleeve is provided in spaced relation an outer sleeve 17 forming an air 4." chamber in which air is heated before circulating into the interior of thel car upon Which the device is applied. This jacket is formed of top and bottom sections each of which comprises a pair of telescopic sections 45 adapted to telescope in orderto adjust the length of the jacket. The ends ofthe outer sleeve 17 are closed by telescopic end members 18 Which are held in position by clamping rings A19. In order to render the casing air .5.0i tight'an asbestos packing is preferably provided between each clamping ring 19 and the inner sleeve 16.

In order to provide a tortuous or circuitous heating chamber for air within the hollow casing, I provide a baille plate 2() which extends toward the front from the rear end of the casing. Said baiiie plate is preferably formed integral with one of the sections of the outer casing 17. An inlet pipe 21 is provided for admitting cold air into the rear end o-f the heating jacket so that air will be caused to travel forwardly beneath the baille and then be permitted to pass outwardly along the passage and through the discharge passage. 22. 'lhis causes the air to be etliciently warmed by heat from the muffler. The inlet pipe 21 comprises apair of telescopic sections, the outer section of which has its end disposed adjacent the front edge of the rear seat and is provided with a slide valve 23 for controlling the inlet of air into the heater. By this construction the cold air will be sucked out of the car as soon as the warm commences to flow thereinto, thereby causing a complete circulation and effecting a heating of the vehicle Without the injection of harmful and obnoxious gases.

A flexible pipe 24 is connected to the discharge passage 22 andhas its opposite end connected with a register, disposed preferably beneath the front seat of the automobile, such register comprising an intermediate secy tion 25 provided with telescopic end sections 26 adapted to be secured in properadjusted position by means oi' bolts 27 carried by the extremities*of the intermediate section and which extend through slots 28 in the end sections. Each of the end sections 26 is provided with a slide valve 29v by means of which the heat may be directed into the front or rear of the car or sinmltaneously through both.

It will beobvious to those skilled in the art that various changes may be made inmy device without departing from thespirit of the invention, and I, therefore, do not limit myself to what is shown in the drawings and described in the speciicatiol, but only as set forth in the appended claims.

Having thus fully described my said'in- .'Tf

vention, what I claim as new and desire to secure by Letters Patent, is:

1. An automobile heater adapted to receive heatJ from the muilier of the automobile for heating air comprising a substantially air tight casing including a pair of spaced concentric sleeves, the outer sleeve of said pair of concentric sleeves being adjustable to vary its length, a partition member formed with one of said sleeves and extending from one end of said casing longitudinally of the same and terminating short of the opposite end, a passage for the admission of cold air 'into one side of said casing adjacent its end,

and an outlet for hot air on the opposite side of said partition at substantially the same 4'end of the casing, substantially as set forth.

2. A device of the class described adapted to receive heat from the muiiler of an automobile for heating air comprising a casing formed of inner and outer sleeves spaced apart to provide an air chamber therebetween, the inner sleeve having overlapping edges for permitting the size of the sleeve to be varied, the outer sleeve comprising telescopic sections adjustable to vary the length thereof, spaced inlet and discharge passages adjacent one end of the casing, and apartition member disposed between said inlet and discharge passages and extending longitudinally of said casing to form a tortuous path for air passing through the casing, substantially as set forth.

3. An automobile heater adapted to receive heat from the mufller of the automobile for heating air comprising an inner sleeve adjustable to various diameters, said sleeve being adapted to fit around the mufiier, an outer sleeve formed of telescopic sections longitudinally ,adjustable to vary the length of the sleeve and in spaced relation to said inner sleeve, means for closing the space between the inner and outer sleeves, and an inlet and a discharge passage on opposite portions of the outer sleeve, substantially as set forth.

4. An automobile heater adapted to receive heat from the muiiler of the automobile for heating air comprising an inner sleeve adjustable to various diameters, said sleeve being adapted to fit around the muffler, an outer sleeve formed o'f telescopic sections longitudinally adjustable to vary the length of the sleeve and in spaced relationto said inner sleeve, means for closing the space be` tween the inner and outer sleeves, an inlet and a discharge passage on opposite portions of the outer sleeve, and partition members disposed on opposite sides between the inner C0 and outer sleeves maintaining the sleeves in spaced relation, substantially as set forth.

5. An automobile heater adapted to receive heat from the muffler of the automobile for heating air comprising an inner sleeve 5 adjustable to various diameters, said sleeve being adapted to lit around the muier, an outer sleeve formed of telescopic sections longitudinally adjustable to vary the length of the sleeve and in spaced relation to said inner sleeve, means for closing the space between the inner and outer sleeves, an inlet and a` discharge passage on opposite portions of the outer sleeve, and partition members disposed on opposite sides between the inner and outer sleeves maintaining the sleeves in spaced relation, the inner sleeve being fitted to the muflier in a manner to permit fumes to escape from its end but preventing the passage of fumes into the space between the inner and outer sleeves, substantially as set forth.

In Witness whereof, I have hereunto set my hand at Portland, Oregon, this 16th day of August, A. D. nineteen hundred and twentyseven.
